We divide 916571 by 77
The aim is to understand the frequency of 77 in 916571.

Let's proceed to step 1:
9 divided by 77 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 77

Moving on to step 2:
77 can be fit into 91 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 77 from 91 to get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 77

Going ahead to step 3:
77 can be fit into 146 1 times, resulting in a remainder of 69.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 77 from 146 to get 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 77

Let's proceed to step 4:
77 can be fit into 695 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtracting 693 from 695 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 77

Going ahead to step 5:
77 goes into 27 0 times with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 1190.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 77

Going ahead to step 6:
77 goes into 271 3 times with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 11903.0
The remainder is 40 after subtracting 231 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
400 divided by 77 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 11903.5
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 77 fits into 150 1 times, leaving a remainder of 73.
The next digit of our result is 1. 
Result so far: 11903.51
Deduct 77 from 150 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 11903.519
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
The number 77 fits into 370 4 times, leaving a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 11903.5194
The remainder is 62 after subtracting 308 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
When dividing 620 by 77, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11903.51948
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
When dividing 40 by 77, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11903.51948
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
If we divide 400 by 77, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 11903.5194805
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
77 goes into 150 1 times with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 11903.51948051
Deduct 77 from 150 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Our division results in 11903.51948051 with a remaining 7.3e-08.
